Fiber optic connection has started to be widely used by many consumers. A fiber optic splitter is a passive optical device used in PON systems. Optical splitters can be divided into Fused Biconical Taper (FBT) splitters and Planar Lightwave Circuit (PLC) splitters.
PLC Splitter has newer and more complex technology than the FBT Splitter. The FBT splitter is made from easily found materials such as steel or fiber. The PLC Splitter is produced using semiconductor technology, which makes production more difficult. The device price is higher compared to the FBT Splitter.
What is a Fiber Optic Splitter?
A fiber optic splitter is a passive optical device that provides distribution between two or more fibers in a fiber optic connection. The fiber optic splitter is one of the most important passive devices in passive optical networks (EPON, GPON, BPON, FTTX, FTTH), allowing a single PIN interface to be shared among many subscribers. Optical splitters are divided into Fused Biconical Taper (FBT) splitters and Planar Lightwave Circuit (PLC) splitters.

What is a PLC Splitter?
A PLC Splitter, also called a planar waveguide splitter, is a device that splits one or two light beams into multiple beams and provides distribution among multiple fibers. It has many input and output terminals to connect the MDF (main distribution frame) and terminal equipment.
The fiber PLC splitter offers a low-cost, highly stable, and reliable light distribution solution. PLC splitters typically provide a higher splitting ratio than FBT splitters. PLC Splitter has a more complex manufacturing technology than the FBT splitter.
PLC Splitter is produced using semiconductor technology, which makes production more difficult. This is reflected in the device price, which is higher. Although the cost of the PLC Splitter is higher than that of the FBT splitter, the PLC Splitter is more reliable.
What is the operating principle of a PLC Splitter?
The 2×64 splitting configuration is more complex than the 1×4 configuration. The optical splitter with a 2×64 configuration has two input terminals and sixty-four output terminals.
Its task is to split two separate input cables into sixty-four light beams and transmit them through sixty-four separate fiber optic output cables. It is important to note that the extracted light beams may or may not have the same optical power as the input light beam. The designer should consider passive optical networks.
The fiber optic PLC splitter is a low-cost solution in passive optical networks. The PLC Splitter design is based on planar waveguide circuit technology, and the main component, the PLC Splitter chip, provides high optical performance. The splitting ratios of PLC Splitters can range from 1×2 up to 64 or from 2×2 up to 64, to meet different subscriber numbers and PON architectures in GPN, EPON, FTTX applications. Additionally, the PLC Splitter package can have a small form factor, adapted to various application environments.
